FIELD: measuring equipment.
SUBSTANCE: fiber optical pressure sensor made on the basis of an optical fiber comprises a housing having a channel for supplying a working medium, terminating with a plug, and an optical fiber with two Bragg gratings and as a sensing element. The plug is made in the form of a membrane, on the reverse side of which racks are made, in which the optical fiber is rigidly fixed. The first section of the optical fiber with the Bragg grating is located between the racks, and the second section of the optical fiber with the Bragg grating is located on the reverse side of the rack.
EFFECT: improving the measurement accuracy.
